Question

The ruling gradient on a stretch of MG track is 0.5%. If a curve of $4^{\circ }$ is also situated on it, the allowable ruling gradient on the curve will be

Answer 1

Ruling gradient = 0.5%

Grade compensation for MG track
$=0.03\times D$
$=0.03\times 4$
$=0.12\%$

$\therefore$Allowable ruling gradient
$=(0.5-0.12)\%$
$=0.38\%$
